Claims

[Scope of utility model registration request]

In a valve train for an internal combustion engine, a rocker arm for opening and closing an intake valve or an exhaust valve is pivoted to a fixed rocker shaft so as to swing in accordance with the rotation of a camshaft. The first oil passage is for supplying lubricating oil to the parts where the sliding load is large, and the second oil passage is for supplying lubricating oil to the parts where the sliding load is large in the high speed operating range of the engine. The first and second oil passages are drilled independently from each other, and supply lubricating oil to the first oil passage at least in the low-speed operating range of the engine, and supply lubricating oil to the second oil passage in the high-speed operating range of the engine. A valve train for an internal combustion engine, characterized in that it is connected to a supply source of lubricating oil.
